sage-way O for the center bar D to be freely moved therein horizontally.

The letters S S designate spiral springs, one of which encircles the bar D on each side 5 of the collar 0 between the latter and the IO beam bar R, the latter at its outer end connecting with the brake-beam B. The upper end of this lever is shown as making a connection by means of a rod (Z with the pistonrod M of an air-cylinder A to operate said This application by means of the lever L adapts my invention to passenger-coaches.

The letter L designates another lever, which at p is pivoted to the end E of the center bar D and at its short arm at p to the brake-beam bar R the latter connecting with the brake-beam 1-3, having thereon the brakes B, which lever L is operated by the usual brake-wheel shaft (not shown) and adapts my invention to freight-cars.

The function of the center bar D as operated by either of the levers L and L is to draw the brake-beams toward the wheels, so that the brakes on the latter will engage with 0 the treads of the wheels at each end of the truck and against the force of a spring, by which latter, when the brakes are thrown off, the brake-beam and brakes are swung out away from the wheels, and this center rod 5 and its levers maybe used in connection with either of the springs S S or the ordinary leaf-springs J, as a modification thereof, in view of the fact that either of the said springs SorS performs the samefunction. As the said 40 center bar D by means of the levers L L and the connection the latter makes with the brake-beams performs the function of putting on the brakes, I do not limit my invention of these factors, as I arrange them to operate, to their combination with the springs 5o ed is as follows: The aircylinder A, being operated to draw the piston in the direction of the indicating-arrow, pulls the lever L in the same direction, which, being at its lower end pivoted to the brake-beam rod R and interi'nediately pivoted to the center bar D,

pulls the brake-beam and brakes toward the wheels and moves outwardly the center bar D against the force of the spring S,while the lever L at its long arm engaging with the .60 cross-brace B operates to move the other end of the center bar D, so as to draw the brakebeam brace R and its connecting-brakes toward the tread of the wheels at the other end of the truck, and when power is applied to the lever L then the center bar D moves to draw adjacent the brake-beam and brakes to engage with the wheel-treads against the force of the spring S while the lever L, at its long arm end engaging with the truck-brace B operates to draw the other brake beam and brakes to engage with the treads of the-other wheels.

As thus made and arranged, a prompt and efficient: operation of the brakes is obtained, and by the use of but few working-pieces.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combi11ation,with a car-truck frame constructed with pendent brake-beams having thereon brakes adapted to engage with the truck-wheel treads at each end of the truck, substantially as described, of a center bar arranged to move horizontally in a yoke or hangers downwardly projected from the truck-frame, a lever pivoted to each end of said center bar where extending beyond said yoke or hangers, and a bar connecting with each of said brake-beams at its outer end and at its inner end pivoted to the short-arm end of the adjacent one of said levers, substantially in the manner as and for the purposes set forth.

2. The combination, with a car-truck frame having cross-braces and constructed with pendent brake-beams having thereon brakes adapted to engage with the truck wheel treads at each end of the truck, substantially .as described, of a center bar arranged to move horizontally in a yoke or hangers, a lever pivoted to each end of said center bar, and a bar connecting with each of said brake-beams at its outer end and at its inner end pivoted to the short-arm end of the adjacent one of said levers, with one of the latter arranged to receive power and the other one of said levers to engage with the adjacent cross-brace of the truck-frame, substz-tntially in the manner as and for the purposes set forth.

The combination, with a car-truck frame constructed with pendent brakebeams having thereon brakes adapted to engage with the truck-wheel treads at each end of the truck, substantially as described, of a center bar arranged to move horizontally in a yoke or hangers, a lever pivoted to each end of said center bar,a bar connecting with each of said brake-beams at its outer end and at its inner end pivoted to the short-arm end of the adjacent one of said levers, and springs arranged to force said brake-beams and brakes away from their contact with said wheeltreads, substantially in the manner as and for the purposes set forth.

Signed at Troy, New York, this 17 th day of August, 1889, and in the presence of the two witnesses whose names are hereto written.
